One avoiding Luke, at last in contact with his father? (6)
I believe the answer is:
evader
But I can't explain it at all! Could you help me understand?
(Other definitions for evader that I've seen before include "One escaping by guile" , "One who avoids tax" , "Person who avoids" , "One who dodges, tax say" , "One avoids or circumvents" .)
